Hi @asalerno , welcome to the community.

Can you explain a bit better what the ‘ the sms chat service “ is? You have a webpage link? 

On what stage is the failure occuring, is it expected to send an sms to your number for validation? 

Hi @eric, thanks!

I mean this service:

In the messages settings I see this below:

If I click on the chat settings (private) I get a failure to register

If I click on the chat settings (office) I see this:

The office sim card is from another provider. 

I Hope this helps, thanks again!

Additional info: my wife has t-mobile physical sim and the chat setting works (on a different phone).

mm, never seen this before. Maybe on your subscription premium sms is blocked? Check in your T-mobile app.

Where can I see it? I have only blocked the ftmsc services, but even enabling those there is no difference.  Do you suggest looking somewhere else?

Thanks

Hi Waqqas,

Yes, but no luck. I suspect the esim might be the culprit...
